A Twilight fanfiction fan girl would adapt in various ways if she dropped into the story. She might initially rely on her fangirling instincts to approach the characters she loves. But as time goes on, she would need to learn the real - life (in - story - life) rules. She'd have to figure out how to deal with the different factions like the Cullens and the werewolves. Maybe she'd start by offering her unique perspective on things, as she has read so many fanfictions and has different ideas. She could also use her modern - day knowledge in some ways, like introducing new forms of entertainment to the characters she befriends, which could help her integrate into the story world.
First, she would have to come to terms with the fact that she's actually in the Twilight world. Then, she might start by trying to fit in with the local humans. Since she knows the story, she could avoid some of the dangerous situations. For example, she'd know to stay away from certain areas at night if she's near the vampires. And she could gradually make her way into the more supernatural aspects of the story by making friends with the right people.
She might first be in shock. Then, she could try to find her favorite characters. Maybe she would try to change the plot to make it more to her liking, like preventing some of the sad parts from happening.
Culturally, it would be a huge shock. Different species have different values. She'd need to adapt to the idea of inter - species relationships and the various religious beliefs. For instance, the Asari have a unique view on reproduction and family that she'd have to understand to fit in.
Hermione would also try to use her magic to her advantage. For example, if she found herself in a dangerous situation with a vampire or a werewolf, she'd use spells for protection. And she'd probably try to educate the characters in the Twilight world about magic, which could be both confusing and exciting for them.
She can start by learning about the powers and personalities of the Avengers. That way, she can figure out how to interact with them. For example, knowing that Hulk gets angry easily, she'd be careful around him.
She would likely adapt by first learning the languages. Since Middle - earth has various languages like Sindarin and Khuzdul. Then she would have to get used to the different cultures and social norms. For example, the strict hierarchies in some of the kingdoms.
She'd have a tough time at first. The lack of modern conveniences like electricity and running water would be a shock. But she might adapt by using her knowledge of history to figure out how to get by. For example, learning to sew clothes in the Camelot way or helping with the farming using basic agricultural knowledge.
She'd have to learn the local languages first. Then she'd need to get used to the different food and living conditions. Maybe she'd start by finding a place to stay, like an inn. And she'd quickly realize she has to learn how to defend herself, so she might seek out training in combat skills.
She would have to quickly learn the rules of Gotham. For example, she needs to know which areas are safe and which are dangerous. And she might start by observing how the people in Gotham interact with each other and with the criminals.
Ruby would need to adapt to the food in the real world. In Remnant, they might have different kinds of food based on their regions and cultures. Here, she'd be introduced to a whole variety of new tastes. She might find some things delicious, like pizza perhaps, but also be really confused by things like fast food chains. Also, she'd have to get used to the currency system. Without any money at first, she'd have to figure out how to earn or get some in order to survive.
If Elsa is transported to the real world in fanfiction, her adaptation would be a journey. Initially, she'd be shocked by the noise and crowds. But she has a strong will. She'd learn about different cultures and languages. She might use her ice powers in creative ways, like making an ice rink in a park. This would help her gain acceptance. And she'd also make friends with those who are kind and curious about her, which would further aid her in adapting to this strange new world.
